IMPROVEMENT IN MACHINES FOR POINTINGPIGKETS.

To ALL WHOM'IT MAY ooNcnRN;

Be it known that I, W. W. JOHNSON, of Nashville, in the county ofDavidson, and State of Tennessee, have invented a. new and improvedMachine for Pointing Pickets, and for similar purposes; and I do herebydeclare that the fOHOWHg S a' full, Cle=1r1lnd exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being hadvto the accompanying drawings, forming part ofthis speciiication, in which- Figure 1 is a side view of my invention.

Figure 2 is a rear end view of the same.

Figure 3 is a. plan. p

Similar letters of reference indicate corresponding parts.

The object of this invention is to point the ends of pickets orfence-palings,`and cut circular sides or edges on other wood-work; andit consists -in attaching an ordinary earpentcrs plane-iron to lan ironframe, on which is pivoted an arm for holding the picket or otherarticle of wood in such a manner that by turning the said arm onitspivot with the picket, the planciron.shall cut and dress one eide of theend in the arc ot' a circle at one movement. v

By this means pickets may be pointed or dressed to shape at the ends,with great expedition and accuracy, saving a great dealof labor requiredby the ordinary manner of performing this work.

A is a stand, to be fastened to a. bench. for supporting the bed-plateBof the machine` On one side ofthe bed-plate B is secured an adjustableclamp, C, in which is held a plane-iron, a, with its edge in a verticalposition; and on the opposite side of the bed-plate a swinging arm, D,is pivotcd at b, to turn horizontally with a sliding and adjustableclamp, E, operated by an eccentric-lever, F, for holding pickets ofdifferent sizes, placed inV the'clamp, as shown in red. 'In front of theplane-iron a is placed an adjustable slidc,.G, agairist which the end ofa picket is placed while it lies in the clamp E, to regulatethe pointingor cutting with thc'plane-iroa.

When the picket is thus placed in position, as shownin the drawings, itis held tight in the clamp E bythe eccentric-lever F, and then, bydrawing upon the outer end ot' the picket, to act as alever, it is swungaround with the arm D in such a manner that the end of the picket is.brought against the edgcof the plaue-iron, and is cut on ono side inthe arc ct' a circle. i

This operation is performed on two or more sides of a picket, which isthus dressed'or pointed quickly and accurately, as shown in fig. 3. Theplane-iron clamp C and'the arinD maybe adjusted to cut the ends of thepickets or other articles in arcs of different diameters.

`Having described my invention, what I elaimgas new, and desire tosecure by Letters Patent, isp The swinging arin D, provided with theeccentric-lever F and the holding-clamp E, when constructed and arrangedto operate the picket against thc knife a, substantially as and for thepurpose herein described.

The above specification of ny invention signed by me, this 3d day ofJune, 1867.
